Mayor Bill de Blasio said Tuesday he doesn’t believe his beloved New England Patriots would cheat by deflating footballs.

“You could have had a brick for a ball, and they would have won that game,” said the mayor, who grew up in Massachusetts and has an affinity for the state’s teams.

He was referring to the Patriots’ final playoff game against the Indianapolis Colts, which the New Englanders won by a lopsided 45-7.

The Patriots are now headed to Sunday’s Super Bowl with the cloud of “Deflategate” hanging over their helmets.

The mayor charged critics are just blowing smoke.

“I also don’t see why you would care to do it. With all due respect to our friends in Indianapolis, why bother to do it against the Indianapolis Colts?” de Blasio added, talking trash about the losers.

Patriots coach Bill Belichick has claimed “atmospheric conditions” may have caused the balls to lose air pressure during the rout — an explanation which scientists have ridiculed.

Hizzoner, who also roots for the Boston Red Sox, acknowledged that he isn’t an impartial observer.

“Obviously I’m a fan and I’m biased, and I really want them to win. And this obviously might be the last chance for Belichick and (quarterback Tom) Brady to win,” he said.

“But I’m saying that just on a logic level, I can’t see the logic of why someone would do that and not think it would be a problem in a society where everything becomes public.”
